as you didn't provided the kde version to which you've upgraded to, I assume it is 4.10, in any case, please upgrade your kernel and then try again._________________Only two things are infinite, the universe and human stupidity and I'm not sure about the former - Albert Einstein

for future reference, try to keep your kernel updated as you keep your DE updated, it might solve a lot of issues._________________Only two things are infinite, the universe and human stupidity and I'm not sure about the former - Albert Einstein
